Quality of water, Quillayute River basin, Washington
M. O. Fretwell
1984, Water-Resources Investigations Report 83-4162
Groundwater in Quillayute River basin is generally of the calcium bicarbonate type, although water from some wells is affected by seawater intrusion and is predominantly of the sodium chloride type. The water is generally of excellent quality for most uses. River-water quality was generally excellent, as evaluated against Washington State...
An assessment of nonpoint-source discharges, streamflow, and water quality in Onion River, Wisconsin
S. J. Field, R.A. Lidwin
1984, Water-Resources Investigations Report 84-4066
The Onion River in eastern Wisconsin was studied during the 1979 and 1980 water years to define the relationship between water quality and streamflow. Agricultural nonpoint-source discharges in the lower part of the Onion River are suspected of contributing significantly to degradation of water quality. Two streamflow water-quality monitoring stations were...
Water resources data, Indiana, water year 1983
R. L. Miller, R.E. Hoggatt, G.E. Nell
1984, Water Data Report IN-83-1
Water resources data for the 1983 water year for Indiana consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels in wells. This report contains discharge records for 174 gaging stations, stage and contents for 9 lake and reservoirs,...
Evaluation of future base-flow water-quality conditions in the Hillsborough River, Florida
Mario Fernandez Jr., C. L. Goetz, J.E. Miller
1984, Water-Resources Investigations Report 83-4182
A one-dimensional, steady-state, water-quality model was developed for a 30.0 mile reach of the Hillsborough River to evaluate water-quality conditions to be expected from future development. The model was calibrated and verified using data collected under critical base-flow conditions in April and December 1978. Dissolved organic nitrogen, nitrate nitrogen, and...
Chemical quality of landfill leachate in treatment ponds and migration of leachate in the surficial aquifer, Pinellas County, Florida
Mario Fernandez Jr., G. L. Barr
1984, Water-Resources Investigations Report 83-4193
The Pinellas County leachate treatment and disposal site encompasses about 8 acres within the 220 acres of the county 's Bridgeway Acres landfill. The site has a high water table and is subject to inundation due to tidal flooding and major storms. Fresh leachate is pumped from V-shaped trenches an...
Water-quality and chemical loads of the Susquehanna River at Harrisburg, Pennsylvania, April 1980 to March 1981
David K. Fishel
1984, Water-Resources Investigations Report 83-4164
Water samples were analyzed for 42 chemical constituents to determine the water quality of the Susquehanna River at Harrisburg, Pennsylvania from April 1, 1980, to March 31, 1981. The investigation was part of the U.S. Environmental Protection Agency's (EPA) Chesapeake Bay Program's Fall Line Monitoring Project to provide information on...
Investigation of ethylene dibromide (EDB) in ground water in Seminole County, Georgia
James B. McConnell, D.W. Hicks, L. E. Lowe, S.Z. Cohen, A.P. Jovanovich
1984, Circular 933
An investigation of ground water in Seminole County, Georgia, for ethylene dibromide (EDB) was conducted in August 1983 by the U.S. Geological Survey in cooperation with the Exposure Assessment Branch of the U.S. Environmental Protection Agency. The purpose of the investigation was to determine whether EDB, which was previously detected...
Evaluation of a hydrograph-shifting method for estimating suspended-sediment loads in Illinois streams
L.R. Frost, L.J. Mansue
1984, Water-Resources Investigations Report 84-4037
A hydrograph-shifting method for estimating monthly and annual suspended-sediment loads was applied to suspended-sediment records for 12 streams in Illinois. Transport equations for each station were developed and synthetic sediment-discharge hydrographs were then generated by using these transport equations and records of daily streamflow. Hydrographs were shifted to measured values...
Measured sections and discussion of the main turbidite member, Middle Pennsylvanian Minturn Formation, northern Sangre de Cristo Range, Custer and Saguache counties, Colorado
S. J. Soulliere, B.L. DeAngelis, D. A. Lindsey
1984, Miscellaneous Field Studies Map 1622-B
Turbidites are sediments deposited by turbid density currents. The turbidites described here are interpreted as prodelta deposits that formed in front of fan deltas and alluvial fans during the uplift of the ancestral Rocky Mountains in Pennsylvanian time. Laterally extensive, lenticular sand bodies deposited by turbidity flows crop out in...
The Georges Bank monitoring program 1983: Analysis of trace metals in bottom sediments
Michael H. Bothner, R.R. Rendigs, Esma Campbell, M. W. Doughten, P. J. Aruscavage, A. F. Dorrzapf, R. G. Johnson, C.M. Parmenter, M. J. Pickering, D. C. Brewster, F. W. Brown
1984, Circular 915
From July 1981, when drilling began on Georges Bank, to May 1982, the concentration of barium, a major element in drilling mud, has increased by a factor of 3.5 in bulk sediments 200 m from the drill site in block 410 and by a factor of 2.3 at the drill...
Sediment Transport in the Lower Yampa River, Northwestern Colorado
John G. Elliott, James E. Kircher, Paul Von Guerard
1984, Water-Resources Investigations Report 84-4141
Discharge measurements and sediment samples were taken at streamflow-gaging station 09260050 Yampa River at Deerlodge Park in 1982 and 1983 to determine the annual sediment supply to the Yampa Canyon in Dinosaur National Monument. Forty-three years of discharge records at two tributary sites were combined to determine the historic discharge...
Hydrogeologic setting east of a low-level radioactive-waste disposal site near Sheffield, Illinois
J.B. Foster, George Garklavs, G.W. Mackey
1984, Water-Resources Investigations Report 84-4183
Core samples from 45 test wells and 4 borings were used to describe the glacial geology of the area east of the low-level radioactive-waste disposal site near Sheffield, Bureau County, Illinois. Previous work has shown that shallow ground water beneath the disposal site flows east through a pebbly-sand unit of...
